Answer:

The two equations are not equivalent and no property is used.

Step-by-step explanation:

54 - (30 - 8) ... (i)

(54 - 30) - 8 ... (ii)

Solving (i) and applying PEMDAS:

We open the brackets first;

54 - 30 + 8 = 54 + 8 - 30 = 32

Solving (ii) and applying PEMDAS:

We open the brackets first;

54 - 30 = 24

24 - 8 = 16

1/2 to the nearest present

Harman [31]

It’s actually 50% because you have to make a proportion 1/2=x/100 multiply the numerator 1 by the denominator 100 and you got 100 then divide it by the other denominator which is 2 so 100 divided by 2 is 50 fill 50 in for x which is 50/100 which means 50%
